specific Embodiment 1

[0031] Specific embodiment 1 of the passenger car of the present invention: the passenger car includes a vehicle frame and a battery pack, such as figure 1 As shown, the top of the vehicle frame is a roof frame 1 , and the side is a side frame 10 , and the battery pack is installed on the roof frame 1 during assembly.

[0032] Specifically, the structure of the roof frame 1 of the vehicle frame is as follows: figure 2 As shown, it includes a cross beam 2 and a longitudinal beam 3, wherein the middle part of the cross beam 2 is straight, and both ends along the width direction of the passenger car are bent into an arc curved toward the side wall frame 10, so that the two ends of the roof frame 1 are Arc-shaped structure, the roof frame 1 is connected with the side frames on both sides of the vehicle frame 1 through the arc-shaped structures at both ends, so that there is a circular arc transition between the two sides of the vehicle body and the top surface.

Abstract

The invention relates to a passenger car. The passenger car comprises a car frame, the top of the car frame is a car roof framework, and the two ends, in the width direction of a car body, of the car roof framework are of arc-shaped structures bent towards side wall frameworks; a battery pack is provided with a plurality of mounting feet, at least part of the mounting feet correspond to the arc-shaped structure of the car roof framework, and the battery pack is fixed to the car roof framework by arranging fixing pieces between the mounting feet and the car roof framework; and the passenger car also comprises damping blocks are supported between the mounting feet and the arc-shaped structure of the roof framework, and the damping blocks support the battery pack and absorb vibration transmitted by the car frame. The car frame supports the battery pack through the damping blocks, vibration transmitted by the car frame can be absorbed, the battery pack is prevented from generating large vibration due to overlarge vibration load, the battery pack is in a stable installation state, and the service life of the battery pack of the passenger car is guaranteed to be qualified.

Description

technical field [0001] The invention relates to a passenger car. Background technique [0002] In the prior art, the battery pack of a bus is generally directly installed on the rigid frame. During the driving process of the bus, the low-frequency vibration generated by the uneven road surface will be transmitted to the battery pack by the tires, suspension, and frame, causing the battery pack to be vibrated. vibration under load. [0003] Especially for the bus with the battery pack installed on the roof, due to the arc transition between the top surface of the bus and the two sides in the width direction of the bus, the profiles at both ends of the top frame of the vehicle frame along the width direction need to be designed and processed into an arc shape , to connect with the arc of the side frame, and the width of the battery pack itself is so wide that the mounting feet of the battery pack correspond to the arc part of the top frame of the vehicle frame. In order to i...
